Add CUDA compute capability 103 to build tools.

Remove unused coordination service protos.

make constants emitted for BitonicSort's comparator internal to module

[XLA:GPU] Add pointer exchange capability to MultiGpuBarrierWithNccl.

[XLA:MSA] Block Prefetching - do not add uses that are not in the same computation as the allocation value to the allocation.
